Buffer Capture

The screen's text buffer can be captured via VT sequence suitable for shell integration, such as fzf.

Request Syntax

CSI > Pl ; Pr t

Pl is 1 if the lines are to be counted logically and 0 if the lines are to be counted visually.

A logical line is may be a wrapped line that spans more than one visual line, whereas a visual line always maps to exactly one line on the screen.

The parameter Pr is the number of lines to be captured.

Response Syntax

PM 314 ; <data> ST

The response is may span multiple PM sequences. The reply will always end with a PM message with an empty <data> block, denoting the end of the reply.

Each <data> chunk will be UTF-8 encoded of the text lines to be captured. Each line will be delimited by a newline escape sequenced (LF).
